What is Nanosilver?

Nanosilver, also known as colloidal silver or silver nanoparticles, are small pure silver metal particles that are being used in a wide range of existing and emerging applications due to their unique and amazing antibacterial, electrical and thermal conductivity, and catalytic properties. As nanoparticles, they range in size (diameter) from 1 to 100 nm and are generally dispersed in a liquid such as water with a stabilizing shell that acts as an emulsifier.

What’s unique about Dune Nanosilver?

Dune Sciences’ NS20D nanosilver is the most versatile, well-characterized, safest, and affordable precision-engineered silver nanoparticles on the market today.

NS20D precision engineered nanosilver has been exhaustively characterized using a wide range of analytical methods to ensure their purity, size, stability, toxicity, and compatibility with other chemicals. We have extensively documented the properties of the particles in a wide variety of formulations and applications.

Acute toxicity testing for dermal, oral, inhalation, eye irritation, skin irritation, and skin sensitization has confirmed that these particles have Category IV toxicity for all tests, which is the safest category assigned by the EPA to any material.

NS20D nanoparticles can be produced in wide range of stable concentrations – from <1 ppm up to an unprecedented >250,000 ppm (25 wt.% silver) in aqueous solutions that can be used to formulate new and/or improved products. Also available as a solvent-free solid that can be dispersed/dissolved in a variety of organic solvents or polymer melts.

Generic silver nanoparticles can be found from a number of other vendors, but you do not know what you are getting in terms of size, purity, or toxicity. Other vendors have well-characterized, precision-engineered silver nanoparticles that are extremely expensive. NS20D products fit in the middle where we have well-characterized particles at an affordable price for researchers and product developers.
